This package provides support for «golden testing».

A golden test is an IO action that writes its result to a file. To pass the test, this output file should be identical to the corresponding «golden» file, which contains the correct result for the test.

To get started with golden testing and this library, see Introduction to golden testing.

Command-line options

To see the command-line options, run your test suite with --help. Here's an example output:

Mmm... tasty test suite

Usage: test [-p|--pattern PATTERN] [-t|--timeout DURATION] [-l|--list-tests]
            [-j|--num-threads NUMBER] [-q|--quiet] [--hide-successes]
            [--color never|always|auto] [--ansi-tricks ARG] [--accept]
            [--no-create] [--size-cutoff n]
            [--delete-output never|onpass|always]

Available options:
  -h,--help                Show this help text
  -p,--pattern PATTERN     Select only tests which satisfy a pattern or awk

                           default: s)
  -l,--list-tests          Do not run the tests; just print their names
  -j,--num-threads NUMBER  Number of threads to use for tests
                           execution (default: # of cores/capabilities)
  -q,--quiet               Do not produce any output; indicate success only by
                           the exit code
  --hide-successes         Do not print tests that passed successfully
  --color never|always|auto
                           When to use colored output (default: auto)

  --accept                 Accept current results of golden tests
  --no-create              Error when golden file does not exist
  --size-cutoff n          hide golden test output if it's larger than n
                           bytes (default: 1000)
  --delete-output never|onpass|always
                           If there is a golden file, when to delete output
